Bridge joint: Many sizes of bridge expansion device, we can make it as your requirement.

Bridge expansion device is a bridge annex, which mainly application in highway, railway and other projects, is a kind of devices on the protection of the bridge expansion device .

The kind and sort of bridge expansion device

It can be divided into six kinds according to the different body structure

1,the type of pure rubber expansion device:

 the body structure is composed entirely of rubber (including special-shaped steel height of less than 50mm and rubber band composed of single-slit)it is used in the volume ≤50mm  

2,The type of bridge expansion device with stuffed plastic body  

We can melt a special elastic-plastic-body rubber, in pouring among the stones

Called “TST bridge device plastic body shell“It is suited the volume<=50mm.

3,The type of board expansion device  

The body structure is made by the rubber, steel or angle sulfide called for the integration of the plate expansion device, it used to the volume<60mm can’t apply to highway projects

4,The type of Polyurethane spring telescopic device:   

It is displace to use of the polyurethane spring and control between the beam and beam tandem installation, suited to the volume of 160 ~ 1200 telescopic device

5,The type of combined expansion devices:  

The expansion body structure is made by rubber plate and steel pallets which  is called

expansion device . It used to less than 120mm expansion volume of road bridges, does not

suited to highway bridges. For example: BF-rubber composite expansion device.

6. The type of modulus expansion device     

The expansion of body structure is combined by steel and rubber seal  which is suited to the volume of 0~ 80 mm 1200 highway for example the type of GQF-MZL and XF type  products.

Major Products and Services:CHINA BAOLI GROUP rubber products includes: rubber water-stop, bridge board-type support, bridge basin-type support, bridge flexible equipment, pneumatic rubber core, rubber dam series and so on.

Because expansion joints are installed at a late stage in construction, some of these movements will have at least partly already taken place. Consequently, expansion joints have to facilitate a smaller degree of overall movement than a bearing at the same location.
Agom deck joints are constructed and designed to prevent damage to the deck, bearings, piers, and abutment by water borne chemicals and other foreign materials, either by preventing water leakage  through the joint or by allowing water to drain through the joint in such a way that avoids damaging the deck, bearings, piers, and abutment.
